Nimbus9 ArcFlow 65W power bank in Bronze Brown at a three-quarter angle on white, its retractable USB-C cable drawn out in a loop and its display lit and reading 100 percent

The cable

It never left the bank.

The USB-C cable winds into the body. Pull it out to charge, let it wind back when you are done. The cable you need is the one already attached.

Nothing to unspool from the bottom of a bag, nothing to leave behind on a hotel nightstand.

  • Retractable USB-C
  • Wound into the body

In use

One bank, four things it does.

Filmed with the ArcFlow 65W: the cable coming out, the display reading itself, the ports filling up, and the part people do not expect.

The cable

Pull. Plug. Let go.

The USB-C cable draws out of the body and winds back when you are done, so the thing you charge with is the thing you carry.

The display

Volts, watts, and what is left.

The readout keeps moving while it works. The number tells you where the charge actually stands, not where it stood when you plugged in.

The ports

More than one at a time.

A USB-C that charges in and out, a USB-A that charges out, and the cable that is already attached — a laptop and a tablet going at once.

Into the wall

It refills itself.

Prongs fold out of the body and it plugs straight into an outlet. Nothing else to pack to fill it back up.

Two views of the ArcFlow 65W in Bronze Brown on white — the front face with its display reading 100 percent, the retractable USB-C connector seated flush at the base and a woven lanyard attached, and the side face with the power button above a USB-C in-out port and a USB-A out port

Display and ports

It tells you what it is doing.

The display on the front reads out while it works, so a slow charge is something you can see rather than something you suspect.

The built-in cable does the heavy lifting and both ports stay live behind it, so a second device plugs in without waiting its turn. A lanyard loop runs off the corner for the days it rides on the outside of the bag.
